Subject [jira] Updated: (DERBY-4964) Client driver fails to convert string to boolean with setObject(col, str, Types.BIT)
Date Thu, 13 Jan 2011 13:08:45 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Knut Anders Hatlen updated DERBY-4964:

    Attachment: mapping-test.diff

Attaching a patch that makes ParameterMappingTest expose the bug. ParameterMappingTest only
tested setObject(int,Object) before. The patch adds testing of setObject(int,Object,int),
which is where the problem is seen. The test passes with the embedded driver and fails on
the client driver when the patch is applied.
